Hi, I cannot reproduce this issue on Ubuntu 16.10 with Terminator-1.90 using your config. I get a terminator window occupying the entire screen, with 2x2 terminals in an equal split.
Your config seems to contain hardcoded pixel values like 3200, 1672, 1600... The exact behavior might easily depend on their relation to the actual screen size. What's your screen size? My one is 1920x1080. e.
